Step by step

Place the dough carefully into a doughnut-shaped baking tin

Tips
The smaller the diameter of your doughnut, the easier it will be to make and, in particular, to move from the work surface to the baking tin.
Trivia
The sweet yeast bread, or 'brioche', is an entirely French 'invention'. It's good both without any filling, or with confectioner's custard or jam.
